Operator then we call t a linear functional on v de nition 47 let v be a normed space over f we denote bvf v recall that bvf is the the space of bounded operators for v to f we can v the dual space of v corollary 48 corollary to theorem 45 for any normed space v we have that v is a banach space in the case of p space where p6 1we can now determine exactly what the . The current set of notes is an activity oriented companion to the study of linear functional analysis and operator algebras it is intended as a pedagogical companion for the beginner an introduction to some of the main ideas in this area of analysis a compendium of problems i think are useful in learning the subject and an annotated reading reference list the great majority of the results
